Abstract: 1403096 Screw centrifuges KLOCKNER-HUMBOLDT-DEUTZ AG 23 Oct 1972 [23 Oct 1971] 48820/72 Heading B2P A solid-jacket centrifuge for separating the liquid and solids constituents of a slurry comprises an outer rotatable centrifuge drum 2, an inner screw-conveyor drum 9 having solidsdischarge-screw flights 10 thereon and rotatable at a speed different from that of the drum 2, a slurry feed pipe 18 at one end of the drum 2 and a solids discharge outlet 3 at its other end, an independently driven slurry-accelerating rotatable body 16 mounted coaxailly within, and radially spaced from, the screw-conveyor drum 9, the body 16 having a feed chamber 21 formed therein in communication with the feed pipe 18 and, through apertures 22 in the body, with the interior of the drum, he feed chamber being traversed by one or more through-flow channels 25 through which clarified liquid can travel axially. In operation, the accelerating body 16 and at least part of the axial extent of the screw-conveyor drum is immersed in the liquid in the drum 2. The slurry to be treated is fed to the chamber 21 through the feed pipe 18 and passes through the openings 22 in the accelerating body 16 and openings 11 in the screw-conveyor drum 9. In addition to being centrifugally accelerated by the screw-conveyor drum 9 and the centrifuge drum 2, the slurry is imparted a higher centrifugal acceleration, starting from the region of the liquid level in the drum, by the accelerating body 16 which is driven at a higher speed than the drums 2 and 9. The clarified liquid moves along the outer wall of the body 16 towards its front edge 30 and then back through the interior of the body and via the channels 25 into a collecting chamber 24 formed in the body where it is scooped off by one or more drain pipes 29 rotating with the drum 2 to be discharged into a chamber 28 in the drum 2 and via openings 31 into a discharge space 32 with centrifuge housing 1. In another embodiment. Fig 2 (not shown), the centrifuge drum and the screw-conveyor drum are frusto-conical and the accelerating body is cylindrical. In a modification of the latter embodiment, Fig 3 (not shown), the accelerating body is frusto-conical and is provided along its inner wall, in the feed chamber, with one or more further flow channels (34) through which part of the liquid which may contain same solids may pass into the collecting chamber (24") and be removed through openings (35) in the end wall thereof for recirculation into the drums (9" and 2").

Title: Telecommunication sender pulse timing control
IPC: H04Q3/54
Filed: 1972-10-31
Abstract: 1406857 Automatic exchange systems GTE AUTOMATIC ELECTRIC LABORATORIES Inc 31 Oct 1972 [24 Nov 1971 3 Jan 1972] 50192/72 Heading H4K In a system incorporating a plurality of register junctors any one of which is allocated to a calling line, the junctors have cyclic access to a dedicated section of a register memory which serves to receive dialled digits and also to control the actions of a sender seized for the call. The memory control is such that each sender transmits autonomously, i.e. it is not tied to a common pulse generator in respect of its pulse start and stop times. In this respect the present system differs from the prior art exemplified by Specification 1,066,921 (USA 3,301,963). Overall control of the exchange is vested in a duplicated stored programme controlled processor using drum and core memories. The register memory is of the non-destructive read-out type utilizing ferrite cores. Each of the 192 provided registers consists of a register junctor, i.e. an interface, which may specialize in local originating or incoming trunk calls and a memory block consisting of sixteen 26-bit words that are read two at a time. The words are used for digit reception (if key calling subscriber or MF trunks are involved a multifrequency receiver is coupled to the register junctor and its output is converted into binary form for storage in the word), storage of routing digits supplied by the processor and control commands such as send dial tone or busy tone, send MF or (Dial) P(ulse), start sending, stop sending, coin test and party test. The processor is accessed by a register following reception of the first three digits so that early outpulsing can occur for a trunk call whereas simple accumulation of a specified number, e.g. seven digits can occur for a local call. In the case of a trunk call the mode MF or DP and the period of interdigital pauses are governed by the type of destination exchange, e.g. common control or step-by-step, and all this data is transferred from the processor into the register words so that the register can control the senders appropriately. The registers and senders have a synchronous duplicated common logic which operates on a TDM basis for giving TDM access between the junctors, memory words and senders and for elementary processing of the words. Normally the two halves of the logic each control one half of the junctors. Although the logic is formed of integrated circuits, the reed relay drivers in the junctors utilize discrete transistor circuitry. The junctor relays used for signalling, e.g. responsive to start/stop sending signals and for repeating dial pulses are of the mercury wetted type.
